Management of Symptomatic Severe Aortic Stenosis in Patient With Very Severe Chronic Obstructive Pulmonary Disease

Transcatheter aortic valve replacement (TAVR) is a viable option for patients with severe chronic obstructive pulmonary disease (COPD) who are deemed inoperable or high risk for surgery. We sought to determine outcomes of patients with severe aortic stenosis (AS) and severe COPD referred for aortic valve replacement (AVR). One hundred thirty-one patients with severe AS and severe COPD (GOLD criteria) were evaluated at our center between 2008 and 2013 and were divided retrospectively into 4 groups: 1-medical management, 2-balloon aortic valvuloplasty, 3-surgical aortic valve replacement (SAVR), and 4-TAVR. Baseline, clinical, and echo data were recorded. Primary outcome was cardiovascular death. From the study cohort, 54 (41.2%), 29 (22.1%), 21 (16.0%), and 27 (20.6%) were included in groups 1-4, respectively; the age was 74.9 ± 8.8, 76.2 ± 8.8, 78.8 ± 7.4, and 82.8 ± 6.8 years, respectively (P < 0.01). There was no significant difference between the groups for hypertension, diabetes, aortic valve area or gradients, forced expiratory volume in first second, right ventricular systolic pressure, ejection fraction, and Society of Thoracic Surgeons predicted risk of mortality score. At 3 ± 1.5 years, death occurred in 87%, 97%, 47.7%, and 51.8% of patients in groups 1-4, respectively. Heart failure readmissions occurred in 43%, 42%, 9.6%, and 14.8% of patients in groups 1-4, respectively. When SAVR and TAVR groups were compared, there was no significant difference in survival (P = 0.719) or heart failure readmissions (P = 0.19). In patients with severe or very severe COPD and severe AS, replacing the severely stenotic aortic valve by either SAVR or TAVR improves survival and reduces rehospitalization compared with medical therapy or balloon aortic valvuloplasty.
